This cycle is characterized by the periodic waxing and waning of sunspot numbers. The Solar Cycle and Sunspot Numbers The Sun does not maintain a constant level of activity; instead, it operates on an roughly 11-year cycle known as the solar cycle.
Future Sunspot Activity Projections: What to Expect in the Next Solar Cycles
The record of sunspot numbers extends back centuries, with observations dating to the telescopic discoveries of Galileo and his contemporaries. By analyzing the magnetic configuration and polarity of sunspot groups, researchers can determine the cycle's phase and anticipate the emergence of large, complex sunspots that are prone to producing solar flares.
Predictive Power and Historical Patterns The regularity of the solar cycle, while not perfectly predictable in its exact amplitude and timing, allows scientists to forecast general space weather conditions. The formation of a sunspot is a direct consequence of the Sun's differential rotation, where the equator spins faster than the poles.

They appear dark because they are significantly cooler—by about 3,000 to 4,500 degrees Celsius—than the surrounding plasma. At the solar minimum, the Sun is relatively quiet, with few or no visible spots.
